View Full Version : Service Your AC Message?

03-19-09, 04:28 PM
So I was driving today and my screen all of sudden pops up a screen that says "service your a/c." The a/c went to off, but the fan was still turning, despite the fact that I hit the a/c on button, it remained that way. Any ideas on the problem?

FYI I have 71k on my 05'.

Sounds like you have a freon leak. I think this message is triggered by the low pressure switch. If the system detects low freon, it will shut down the compressor to prevent it from burning up!

Interesting I had the same problem last fall (I live in MI so it has not yet been fixed). Curious to hear the result. I fully charged and checked the R134a pressure with no improvement.

Of course I've reprogrammed the car a few times since then . . . . . so the message is gone.

Do you have Corvette FRCs?

If so you probably severed a wire, check near the edges I cant remember where it was. Happened to me and others.
